Interface FriendlySelectionService

All Superinterfaces:

Disposable

All Known Subinterfaces:

PortalFriendlySelectionService, PortletFriendlySelectionService

public interface FriendlySelectionService
extends Disposable

Service that helps to work with friendly selection. The service allows to encode and decode friendly selection prefixes to and from portal pages. In addition it is possible to generate URLs in a special friendly URL format.

Note that this interface extends Disposable, it needs to be disposed explicitly before leaving scope by calls to Disposable.dispose()

Since:

6.1.0

Method Summary

SearchableTreeModel<NavigationNode>	getSearchableTreeModel() Returns the SearchableTreeModel used to encode and decode friendly selections.
FriendlyURLFactory	getURLFactory() Returns access to the URL generation functionality for friendly URLs.
boolean	pathEquals(java.lang.String friendlyPath, Identifiable node) Checks if the friendly path that is passed in as a parameter matches the friendly path that corresponds to the node.
boolean	resolve(SelectionResult res, java.lang.String path) Convenience method that converts the complete path string into a SelectionResult.
boolean	resolve(SelectionResult res, java.lang.String path, int off, int len) Converts from a path to a list of ObjectID of selections
boolean	java.io.Writer, com.ibm.portal.navigation.NavigationNode)">write(java.io.Writer out, NavigationNode node) Encodes the friendly selection string from a node.

Method Detail

getSearchableTreeModel

SearchableTreeModel<NavigationNode> getSearchableTreeModel()

Returns the SearchableTreeModel used to encode and decode friendly selections. The model will typically be based on the navigation model for the current user but might differ from it if nodes in the navigation model are hidden from the friendly name hierarchy.

Returns:

the tree model, not null

getURLFactory

FriendlyURLFactory getURLFactory()

Returns access to the URL generation functionality for friendly URLs. The FriendlyURLFactory is part of the instance of the service and does not need to be disposed separately.

Returns:

factory to create friendly URLs, not null

resolve

boolean resolve(SelectionResult res,
                java.lang.String path)
                throws ModelException

Convenience method that converts the complete path string into a SelectionResult. See #resolve(SelectionResult, String, int, int, SearchableTreeModel, Object) for more details.

The friendly path corresponds to the string generated by the java.io.Writer, com.ibm.portal.navigation.NavigationNode)">write(Writer, NavigationNode) method, i.e. it must contain a correctly escaped URL prefix.

Throws:

ModelException

resolve

boolean resolve(SelectionResult res,
                java.lang.String path,
                int off,
                int len)
                throws ModelException

Converts from a path to a list of ObjectID of selections

.

The friendly path corresponds to the string generated by the java.io.Writer, com.ibm.portal.navigation.NavigationNode)">write(Writer, NavigationNode) method, i.e. it must contain a correctly escaped URL prefix.

Parameters:

res - bean that contains the resulting list of selections

path - path string to decode

off - first valid character in the path string, should point to the starting slash

len - length of the valid segment

Returns:

true, if the complete path could be matched, else false

Throws:

ModelException - - if the path could not be resolved

java.io.Writer, com.ibm.portal.navigation.NavigationNode)">

write

boolean write(java.io.Writer out,
              NavigationNode node)
              throws java.io.IOException,
                     ModelException

Encodes the friendly selection string from a node. The node must be part of the TreeModel returned by getSearchableTreeModel(). In case the friendly name cannot be generated the method returns false and no output is written to the writer.

The generated friendly path will be URL escaped, i.e. characters that are not valid for the URL are replaced by their UTF8 based % escapes.

Parameters:

out - target writer to write the friendly string to

node - node to encode, not null

Returns:

true if the node has a friendly name, else false.

Throws:

java.io.IOException - - if the friendly name could not be generated

ModelException - - if the model could not be accessed

pathEquals

boolean pathEquals(java.lang.String friendlyPath,
                   Identifiable node)
                   throws java.io.IOException,
                          ModelException

Checks if the friendly path that is passed in as a parameter matches the friendly path that corresponds to the node. If the friendlyPath is null or the empty string and the node is not represented by a friendly path, then this method returns true.

The friendly path corresponds to the string generated by the java.io.Writer, com.ibm.portal.navigation.NavigationNode)">write(Writer, NavigationNode) method, i.e. it must contain a correctly escaped URL prefix.

Parameters:

friendlyPath - path to check, may be null

node - the identifiable to check for. This node does not necessarily need to be part of the model. Must not be null

Returns:

true if the path matches, else false

Throws:

java.io.IOException

ModelException
